Abstract
The rotational spectrum of the weakly bound complex OCS CO2 has been measured using a pulsed beam Fourier transform microwave spectrometer. The rotational constants of the major isotopomer are A=4454.606 MHz, B=1517.778 MHz, and C=1129.666 MHz. The molecule is planar with a ‘‘slipped near parallel’’ structure analogous to the structure of the dimer of carbon dioxide. The sulfur atom occupies the ‘‘inner’’ position; this is the obtuse rather than the acute vertex of the O–O–O–S quadrangle. The distance from the center‐of‐mass (c.m.) of CO2 to the c.m. of OCS is 3.552 Å.Keywords
